| Abstract: | In order to effectively prevent coal roof water disaster,comprehensive assessment on coal roof water bursting risk in karst area were established on the basis of systematical analyses of water abundance characteristics of aquifer in coal seam roof,structural features,water-resisting ability for aquifuge,effects of mining disturbance on coal seam roof,by the aid of fuzzy comprehensive evaluation.Meanwhile,the coal roof water bursting risk was generally evaluated according to the practical situation of Qinglong coal mine of Qianxi area in Guizhou province.Evaluation results are consistent with the actual situation,indicating the feasibility and accuracy of this method. |
